I was lucky enough to be given (an original!) one of these, as well a Donkey Kong and Donkey Kong II, this weekend. It’s the best Game & Watch game and although I have a keyring mini replica I haven’t played the G&W classic since it was a Hot Product in the school playground.
And it still stands up really well today. Although it was much, much easier than I recall because I managed to complete it on my first go. Actually completing G&W games is unusual because most are high score chaser games, but Zelda has an endpoint – get all the bits of triforce by killing all the dragons – and that’s what I did. It was Excellent.
